    I don't see any reason why it shouldn't work. (I have not looked at the specific datasheets.)

    according to the spec sheets the only thing i can see is that the clock speed for the st is 1mhz and the m is 2 mhz. so im guessing that the m will run happily with a 1 mhz clock.or does it mean it has to be 1mhz???

    You can operate a component at a lower speed.
    Running a component at a speed higher that its rated speed is not recommended.
